Create and manage instant snapshots

This document explains how to create and manage instant snapshots. Instant snapshots capture the contents of a disk and can be used to create a new disk in minutes.

Instant snapshots are stored in the same zone or region as their source disks and are not a replacement for standard snapshots, which offer off-site backup for disaster recovery. Learn about the other data protection options available in Compute Engine.

To access the data on an instant snapshot, use the instant snapshot to create a new disk.

If you want to copy an instant snapshot to another location or retain the snapshotted data after the source disk is deleted, create a standard snapshot from the instant snapshot.

Before you begin

Review the instant snapshot limitations to make sure instant snapshots are suitable for your use case.
If you haven't already, then set up authentication. Authentication is the process by which your identity is verified for access to Google Cloud services and APIs. To run code or samples from a local development environment, you can authenticate to Compute Engine by selecting one of the following options:

Select the tab for how you plan to use the samples on this page:
Console

When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.
gcloud
1. Install the Google Cloud CLI, then initialize it by running the following command:
```
gcloud init
```
  Note: If you installed the gcloud CLI previously, make sure you have the latest version by running gcloud components update.
2. Set a default region and zone.
REST

To use the REST API samples on this page in a local development environment, you use the credentials you provide to the gcloud CLI.
For more information, see Authenticate for using REST in the Google Cloud authentication documentation.

Required roles and permissions

To get the permissions that you need to create instant snapshots, ask your administrator to grant you the following IAM roles on the project:

Compute Instance Admin (v1) (roles/compute.instanceAdmin.v1)
To connect to a VM that can run as a service account: Service Account User (v1) (roles/iam.serviceAccountUser)

For more information about granting roles, see Manage access to projects, folders, and organizations.

These predefined roles contain the permissions required to create instant snapshots. To see the exact permissions that are required, expand the Required permissions section:

Required permissions

The following permissions are required to create instant snapshots:

To create an instant snapshot: compute.instantSnapshots.create
To view instant snapshots: compute.instantSnapshots.list
To view instant snapshots details: compute.instantSnapshots.get
To delete an instant snapshot: compute.instantSnapshots.delete

You might also be able to get these permissions with custom roles or other predefined roles.

Create an instant snapshot of a Persistent Disk volume

Instant snapshots of zonal disks are stored in the same zone as the source disk. Likewise, instant snapshots of regional disks are stored in the same regions as the disk.

You can create an instant snapshot of a zonal or regional Persistent Disk volume using the gcloud CLI, Google Cloud console, or REST.

Console

In the Google Cloud console, go to the VM instances page.

Go to VM instances
Select the project you want to work with.
In the Name column, click the name of the VM attached to the disk you want to back up.
In the Storage section, select a disk in one of the following ways:
- To back up the VM's boot disk, in the Boot disk section, click the Name of the boot disk.
- To back up an attached Persistent Disk volume, in the Additional disks section, click the Name of the attached Persistent Disk volume.
To finish creating an instant snapshot, on the Create a snapshot page, do the following:
1. In the Name field, enter a unique name to identify the instant snapshot.
2. Optional: Add more details about the snapshot in the Description field.
3. In the Type field, select Instant snapshot. The Location field is automatically set to the same zone or region as the disk.
4. In the Snapshot source type field, verify that Disk is selected.
5. Optional: To organize your project, add one or more labels.
6. Click Create.

gcloud

To create an instant snapshot, use the gcloud compute instant-snapshots create command:

Zonal disk

To create an instant snapshot of a zonal disk:

 gcloud compute instant-snapshots create INSTANT_SNAPSHOT_NAME \
   --source-disk=SOURCE_DISK_NAME \
   --zone=SOURCE_DISK_ZONE

Replace the following:

INSTANT_SNAPSHOT_NAME: a unique name for the instant snapshot.
SOURCE_DISK_NAME: the name of the source disk.
SOURCE_DISK_ZONE: the zone of the source disk. The instant snapshot will be created in the same zone.

Regional disk

To create an instant snapshot of a regional disk:

 gcloud compute instant-snapshots create INSTANT_SNAPSHOT_NAME \
   --source-disk=SOURCE_DISK_NAME \
   --region=SOURCE_DISK_REGION

Replace the following:

INSTANT_SNAPSHOT_NAME: a unique name for the instant snapshot.
SOURCE_DISK_NAME: the name of the source disk.

}
```
Replace the following with the corresponding values:
- PROJECT_ID: the name of the project containing the disk.
- DISK_ZONE: the zone where the disk is located. the instant snapshot will be created in this zone.

Change the storage location of an instant snapshot

An instant snapshot is always stored in the same location as the source disk. You can't make an instant snapshot accessible from a different zone or region. Instead, you can create a standard snapshot from the instant snapshot and use the standard snapshot.
